Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Learning addition with more than one digit can be difficult and we hope to help students learn to regroup when needed in this fun video. Kids will learn how to regroup by borrowing from the next place value and will have fun learning the material.
2-Digit Addition doesn\'t have to be difficult. You just need to learn how to regroup! Also known as carrying, regrouping is what we need to do when the numbers we add in one column add up to 10 or more.
